CHISQ.INV(probability, degrees_freedom)

Returns the probability of getting greater than a particular value in a chi-squared distribution (left tailed).

probabilityThe probability associated with the distribution.
degrees_freedomThe number of degrees of freedom.

Remarks

* Added in Excel 2010.
* The chi-squared distribution is a continuous distribution.
* If "probability" < 0, then #VALUE! is returned.
* If "probability" > 1, then #VALUE! is returned.
* If "probability" is not numeric, then #VALUE! is returned.
* If "degrees_freedom" is not an integer, it is truncated.
* If "degrees_freedom" < 1, then #NUM! is returned.
* If "degrees_freedom" > 10^10, then #NUM! is returned.
* If "degress_freedom" is not numeric, then #VALUE! is returned.
